CIRCUIT FOR APPLYING SUPPLEMENTARTY VOLTAGES TO RF MULTIPOLE DEVICES |
摘要 |
A circuit is described for applying RF and AC voltages to the elements or electrodes of an ion trap or ion guide. The circuit includes an RF transformer having a primary winding and a secondary winding. The secondary winding includes at least two filars. A broadband transformer adapted to be connected to a source of AC voltage applies AC voltage across the low-voltage end of two of the filars. Another broadband transformer connected to the filars at the high-voltage end provides a combined RF and AC output for application to selected electrodes. Also described is a circuit employing a multi-filar RF transformer and broadband transformers for applying RF and AC voltages to spaced rods of a linear ion trap. Also described is a circuit employing a multi-filar RF transformer and broadband transformers for applying RF and AC voltages to the electrodes in each section of a linear ion trap of the type having a center section and end sections, and different DC voltages to the electrodes in the end sections.
